Figure 1: LVA extension<0.5mV: comparison between maps in AF and maps in SR.

Figure 2: LVA extension<0.3mV: comparison between maps in AF and maps in SR.

Figure 3A: Comparison between AF and SR maps for the 0.3 mV threshold. Postero-anterior projection. Patient 1.

Figure 3B: Comparison between AF and SR maps for the 0.5 mV threshold. Postero-anterior projection. Patient 1.

In both images, we observed an appropiate match in LVA location, although LVA extension is greater in the AF map.

Figure 4A: Comparison between AF and SR maps for the 0.3 mV threshold. Superior projection. Patient 2.

Figure 4B: Comparison between AF and SR maps for the 0.5 mV threshold. Superior projection. Patient 2.

In both images, we observed lack of LVA in SR maps, for 0.3 mV threshold as well as for the 0.5 mV threshold. In this case it is not possible to assess if LVA location matches appropriately.
